1. A device for effecting multiple scarifications on spaced apart portions of a body comprising:
- a self-supporting body having a convexly curved rolling surface and a plurality of scarifiers extending outwardly of said rolling surface, in spaced apart relationship, said scarifiers having outer scarifying ends,said rolling surface being adapted to be rolled on a body portion for sequential penetration of the epidermis at spaced apart cutaneous sites, by said scarifying ends.

Abstract
A device for effecting multiple scarifications on spaced apart portions of a body has a rolling surface and a plurality of scarifiers extending outwardly of the rolling surface, in spaced relationship; the scarifiers sequentially penetrate the epidermis at spaced apart cutaneous sites when the rolling surface is rolled on the body part; in use the scarifiers support different freeze-dried allergen preparations on their outer scarifying ends.

19. A method of effecting multiple skin tests sequentially which comprises:
-
rolling against a body part a self-supporting body having a convexly curved rolling surface and a plurality of scarifiers extending outwardly of said surface in spaced apart relationship, said scarifiers having outer scarifying ends and supporting at said ends a plurality of different freeze-dried allergen preparations so that said scarifiers sequentially penetrate the epidermis at spaced apart cutaneous sites, applying said allergen preparations to said spaced apart scarified cutaneous sites, and evaluating any reaction at said sites. - View Dependent Claims (20, 21, 22)
